AUGUST w.',wAasnN, or NEW YORK, N. Y.

Be it known that I, AUGUST \Vt-WARSEN, a citizen of the United States, and a resident of New York, borough of Brooklyn, in the county of Kings and State of New York,

of which the following is a full,'clear, and

exact d escription.

The invention relates to crushers of the jaw type; and the object thereof is to provide a simple, strong, and inexpensive crusher by meansof which material can be crushed to varying sizes, "not exceeding a predetermined maximum.- r i I obtainthe above object by providing a frame having a fixed jaw and an oscillatinglever in the frame having. a jaw adapted to coact with the fixed jaw of the frame, the said lever being adjustably mounted in said frame and adapted [to be reversed in v the same. Furthermore, the means-for acdescribed .5h

tuating said lever are .so connected to the same as to prevent a rupture in any of the moving parts of the crusher when an object of high resistance is located between the crushing jaws l I I The inventio consists of the construction and combination of parts to be more fully ereina-fter and. fully set forth in the .cla i is'to be had to the accompanying dra gs -forming a part of this specificatiOn H which like characters indicate *lcorresponding parts n all the views and in Which:

Figure 1 is a'plan View of an embodiment of my invention is a section on line 2--2, Fig. 1=; F1fg; -8 shows the oscillating lever in invertedposition and'Fig. 4 shows a modified structure of a connection between the lever and the connecting rod.

Referring to the drawings fi represents a frame, in the transverseportlon {l ef-which is removably positionedafixed jaw 7. The frame 5 in the longitudinal sides thereof is provided with rectangular apertures 8 and 9 superposing eachother and adjacent the said transverse portion 6. Said apertures 8 and 9 extend also through lateral projections 10 and 11 respectively formed on'the outer face of each of the sides of the frame 5. Positioned in theapertures 9 are hearing blocks 12 in which is mounted to journal a shaft 13. Mounted rigidly on the shaft 1 Patented J l ne 23, 1914.

receives 'ajaw 7 similar to the jaw 7 and facing the same. lever 14 is cored out and forms a central rib 14, thus lightening t-lielever without in any way reducing its strength; and the end of the lever remote from where the jaw 7 is remova'bly secured'is provided with a recess 16. Fitting snugly into the recess is a pro jection 17 formed on an arm 18 which is secured to the lever 14 by means of bolts 19 positioned in the end of the arm 18 remote from the projections. The bolts 19 project through the lever 14 into the cored-out space. A compressionvcoil spring 20 positioned on each of the bolts maintains the arm 18 in contact with the lever 14. The arm 18 is also provided with a recess 21 at the end where the projection 17 is provided but 'on the opposite side, and is engaged by the end of the connecting rod 22. The said rod 22 has a removable portion 23 engaging the recess 21, which'can be replaced when the same is worn out. as can be easily seen from the drawings. The crank-shaft 24, positciloned in the frame, carries the connecting r0 2.

The end of the lever 14 overhanging the above the lever 14 carries a coil spring 27 under compression, normally forcing the lever 14 and the arm 18 therewith in engagemerit with the connecting rod 22. The projection 17 of the arm, which journals in the recess 16 of the lever, has its center of journal so related to the center of the journal formed between the recess 21 and the connecting rod 22 that the two centers under no circumstances come in a straight line with the center of the crank shaft 24, as can be seen from Figs. 2 and 3. This construction permits the arm 18 to turn on its projection 17 in the recess 16 of the lever when an object of high resistance falls between thel ws 7 and 7 during the movement of the crank shaft 24. That is to say, when such an object is engaged between the jaws the lever 14 remain immovable, While the arm 18, under the action of the connecting rod, will oscillate on the lever'14, causing an alternate compression and relaxation of the springs 20 during it: movement. The coinpress ve resistance or the springs 20 is less The major part of they than the resistance to rupture of the lever 14., so that no damage to any of the moving parts can take place when an object of high resistance islocated between the jaws 7 and 7 during the movement of the lever.

The bearing blocks 12 carrying the shaft 13, and the bearing blocks 3% carrying the crank shaft 21, are mounted adjustably in respective apertures provided in the frame.

The adjustment of these bearing blocks is obtained by means of screws 28 provided in the frame, and also plates 29 fitting into the respective apertures where blocks 12 and 34 are positioned. These plates 29 may be of different thicknesses, so as to permit certain relative adjustments of the shaft 13 and also of the crank shaft 2-l. As, for example, when the shaft 13 is moved by the the upper ends of the jaws 7 and 7 will aping rod 31.

preach each other and the crusher will ad- .mit material of smaller size than that shown in Fig. 2; also, the 'jaw 7 will move closer to the jaw 7.

In Fig. 3 the lever 14 is shown in inverted position, that is, the bearing blocks 12 of the shaft 13 are positioned in the aperture 8. This necessitates a displacement of the bearing block 34: and also of the bolt 25, the bolt 25 being then positioned in the lower transverse portion 35 of the frame, while the crank-shaft 24 is moved up toward the upperportion of the frame,'as shown in Fig. 3. This displacement of the lever 14 permits the crushing of material of large size, that is, of variable sizes from as large as the distance between the plates at the upper portion of the frame, to as small as the distance between the lower ends of the plates, as seen in Fig. 3. While the lever is in the position as seen in Fig. 2, 'the material crushed will have a size limited by the distance between the plates at the lower end of the same. mounted adjustably in the aperture 8. r

In Fig. 4 a modified structure of the connecting rod 22 is shown, in which case the lever 14 is not provided with an arm 18 but is directly e zjaged in its recess 16 by a member 30 adapted'to oscillate on a connecting rod 31 but which is prevented from the same normally by a coil spring 32' positioned on the bolt 33 secured to the connect- In this case when the crushing jaws engage an objectof high resistance, endangering the machinery, the member 30 will oscillate on the connecting rod 31, caus- The bearing block 12 is also ing the compression of the spring 32, there-- I by leaving the lever 14, in this case, immovable. As can be seen, the effect is the samein this case as in that previously described,

shaft 24 is very important in crushing machines, as the momentum generated in the moving parts of the crusher by the fly-- wheels positioned [on the crank-shaft 24 would ordinarily rupture some of the moving-parts when an object of high resistance is engaged between the jaws and no resilient connection is provided as disclosed in the above specification.

As shown in the drawings, the crushing plates or jaws 7 and 7 have Wavy surfaces forcrushing, the central portion of which 0 is concave, while th portions a and b be.-

tween the ends are convex.- The parts a and b of the aws will work most and, therefore, the plate will become flat after long service, The convex portions a and b, in which case, will be worn tothe same level as theconc ave portion 0 of the plate. As described, by means of. the adjustmentfof v the, bearing blocks, and also by the-pro+ vision of 'superposed"'apertures 8 and 9 in the frame, material-can be crushed toa predetermined size when in position shown in Fig. 2, or to a different size when the lever is in position as shown in Fig. 3. This structure gives a large latitude in application."
